Danish movie where a man offers to pay a female friend to have sex with him

A Danish movie, though I suppose it may have been Norwegian, Swedish, Icelandic or Dutch.

At the beginning of the movie they are at a bar or a restaurant and a man offers to pay a female friend of his to have sex with him. They then went on a trip and stayed in a hotel.

Think maybe the movie ended with the woman leaving the money for a hotel cleaner.
